NITED STATES PATENT FFICE.

GEORGE W. THOMPSON, OF RIPLEY, OHIO.

IMPROVEMENT IN REVERSIBLE PLOWS.

Specification forming part of Letters Patent No. 110,692, dated January3, 1871.

Toall whom it may concern:

Beit known that I, GEORGE W. THOMPSON, of Ripley, in the county of Brownand State ot' Ohio, have invented a new and Improved Reversible Plow;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawing,forming part of this specification. Y

My invention relates to reversible doublemold-board plows; and has forits objects certain improvements thereon, which will rst be described inconnection with all that is necessary to a full understanding thereof,and then clearly specified in the claims.

Figure l is a side View of my improved plow, and Fig. 2 is a front viewof the same.

Similar letters of reference indicate corresponding parts.

The double mold-board is made in two parts, A B, of sheet metal, andjoined together on the line G, where they are secured by rivets or boltsto the oscillating brace D, by which they are supported from the beam.

The mold-board thus formed is supported on the brace E, and the latterjournaled ou the post F in the usual way.

The advantage of this construction of the mold-board is in thesimplicity and cheapness ot' construction and the facility it aiords ofrepairing` one part or substituting a new one without disturbing theother.

The two parts are readily formed by suitably bending up the edges G andH, which may be done by a drop-press or any simpler form of bendingapparatus.

The improvement in the revolving brace D consists in bending it to theland-side from the line of the colter of the plow, as shown at I, forthe purpose of allowing more freedom for the straw, weeds, and otherlike matters, which I find, in practice, prevents clogging to a verygreat extent.

Having thus described my invention, I claim as new and desire to secureby Letters .Patent- 1. A double reversible mold-board, combined with abrace, E, constructed and arranged as and for the purpose described.

2. The combination, with the mold-board and beam of a reversible plow,ot' the support D, bent at I toward the land-side and from the colter toprevent clogging, as described.

GEO. W. THOMPSON.
